The listing, Train Valley [Steam key] Very Nice game! has ended.
Build railroads in order to connect cities, tunnels and bridges. New railways are cheap when laid across bare fields, but can be expensive when demolishing forests, villages and other existing structures.
Manage increasing traffic by constructing, switches, sidings and spurs so that multiple trains can run without delays, at the same time.
Stay accident-free by precisely controlling trains during crucial moments, using pause for planning (you can build railways and schedule trains while on pause).
Play through 4 seasons: Europe (1830–1980), America (1840–1960), USSR (1880–1980) and Japan (1900–2020).
